Abstract
The utility model discloses a high-voltage cage-shaped motor copper end ring integral forming structure, which comprises a rotor shaft and a rotor iron core. The rotor iron core is formed by overlapping multiple groups of rotor punching sheets, the multiple groups of rotor punching sheets are provided with rotor guide strips penetrating transversely, two ends of the rotor shaft are provided with guide strip end rings, outer peripheries of the rotor punching sheets are provided with annular ventilating grooves, the end rings are in cast forming through dies at two ends of the rotor iron core, and two ends of the rotor guide strip are respectively inserted into the end rings so as to be cast with the end rings integrally. The high-voltage cage-shaped motor copper end ring integral forming structure is fine in mechanical property and attractive in appearance, meets welding requirements of a high-voltage cage-shaped motor upon the end rings, and resolves problems that bars of the motor are easy to be broken during an operation process of the motor, and the motor is overhigh in loss and temperature rise caused by welding shortages.
Description
Technical field:
The utility model relates generally to a kind of high pressure cage modle Cu end ring of motor structure, relates in particular to a kind of high pressure cage modle Cu end ring of motor global formation structure.
Technical background:
High pressure cage modle motor rotor construction is a squirrel-cage, promptly is that sliver and end ring are formed mouse-cage type.Sliver in squeezing into rotor after, now be generally manual silver brazing or adopt the intermediate frequency welding machine to weld, manual silver brazing advantage is: equipment is simple, and technology is simple; Shortcoming is: labour intensity is big, can't guarantee the demand that welding quality requires and produces in batches.Intermediate frequency welding: equipment has high input, and complex process can't satisfy the demand of batch process.The rotor of manual silver brazing and intermediate frequency welding can't guarantee welding process requirement, is difficult to detect whether satisfy the end ring welding requirements, so be prone to disconnected bar phenomenon in motor operation course; Moreover, no matter make and how to weld, all need silver solder, manufacturing cost also increases accordingly.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of defectiveness, a kind of high pressure cage modle Cu end ring of motor global formation structure is provided, adopt specific mould to utilize the method for centrifugal casting at the iron core two ends, sliver and end ring are closely become an overall structure, solved motor in running owing to the solid phenomenon that occurs disconnected bar of not prison welding, and make the loss of electric machine is excessive and temperature rise is too high problem etc. because of weld defect.
The utility model is achieved through the following technical solutions:
A kind of high pressure cage modle Cu end ring of motor global formation structure, include armature spindle, rotor core, described rotor core is formed by many group rotors punching closed assembly, in described many group rotors punching the rotor bar that crosses is arranged, and there is the sliver end ring at described armature spindle two ends, on the described rotor punching excircle loop vent groove is arranged, the die casting moulding of described end ring by the rotor core two ends, and the rotor bar two ends insert respectively in the end ring, pour into an integrated entity with end ring.
Described a kind of high pressure cage modle Cu end ring of motor global formation structure, it is characterized in that: described rotor bar is the copper sliver.
Described end ring forming method is the casting mold in the two ends of rotor core difference mounting circular ring shape hollow, described casting mold is provided with the sprue gate, the two ends of described rotor bar are inserted and secured in the casting mold, gate spool is inserted at the sprue gate, inject liquid metal copper from gate spool, liquid metal copper is integrated poured copper end ring under centrifugal action, and described copper end ring contains the sliver insertion end fully.
The utility model has the advantages that:
The utility model good mechanical property, good looking appearance, satisfied high pressure cage modle motor opposite end ring requirement of welding, solved motor in running because the phenomenon of the solid bar that occurs breaking of not prison welding, and because of weld defect make the loss of electric machine excessive with the too high problem of temperature rise.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
A kind of high pressure cage modle Cu end ring of motor global formation structure, include armature spindle 1, rotor core 2, rotor core 2 is formed by many group rotors punching 3 closed assemblies, the rotor bar 4 that crosses is arranged in many group rotors punching 3, on rotor punching 3 excircles loop vent groove 6 is arranged, there is sliver end ring 5 at armature spindle 1 two ends, described end ring 5 is separately installed with the casting mold 7 of circular hollow by rotor core 2 two ends, casting mold 7 is provided with sprue gate 8, the two ends of rotor bar 4 are inserted and secured in the casting mold 7, gate spool 9 is inserted at sprue gate 8, inject liquid metal copper from gate spool, liquid metal copper is integrated poured copper end ring 5 under centrifugal action, and described copper end ring 5 contains firmly sliver 4 insertion ends fully.
